New and Poorly Known Perisphinctoidea (Ammonitina) from the Upper Tithonian of Le Chouet (Drôme, SE France)
Volumina Jurassica, 2014, Xii (1): 113–128 New and poorly known Perisphinctoidea (Ammonitina) from the Upper Tithonian of Le Chouet (Drôme, SE France) Luc G. BULOT1, Camille FRAU2, William A.P. WIMBLEDON3 Key words: Ammonoidea, Ataxioceratidae, Himalayitidae, Neocomitidae, Upper Tithonian, Le Chouet, South-East France. Abstract. The aim of this paper is to document the ammonite fauna of the upper part of the Late Tithonian collected at the key section of Le Chouet (Drôme, SE France). Emphasis is laid on new and poorly known Ataxioceratidae, Himalayitidae and Neocomitidae from the upper part of the Tithonian. Among the Ataxioceratidae, a new account on the taxonomy and relationship between Paraulacosphinctes Schindewolf and Moravisphinctes Tavera is presented. Regarding the Himalayitidae, the range and content of Micracanthoceras Spath is discussed and two new genera are introduced: Ardesciella gen. nov., for a group of Mediterranean ammonites that is homoeomorphic with the Andean genus Corongoceras Spath, and Pratumidiscus gen. nov. for a specimen that shows morphological similarities with the Boreal genera Riasanites Spath and Riasanella Mitta. Finally, the occurrence of Neocomitidae in the uppermost Tithonian is documented by the presence of the reputedly Berriasian genera Busnardoiceras Tavera and Pseudargentiniceras Spath.

00 o Riv. Ital. Paleont. > n . 2 pp. 193-250 tav. 19-20 Milano 1974 PHYLLOCERATINA (AMMONOIDEA) DEL PLIENSBACHIANO ITALIANO N e r in a F a n t i n i S e s t i n i Abstract. This paper concerns thè conclusive researchs on Pliensbachian Phyllo- ceratina from Italy, among which thè genera Geyeroceras Hyatt, 1900 and Partschiceras Fucini, 1923 were already investigated (Fantini Sestini, 1969, 1971). The fossils were collected in stratigraphic sections from Selva di Zandobbio and Alpe Turati in Lombar- dy and from thè M. Nerone area in thè centrai Apennines. They consist of internai moulds and complete shells. The family Juraphyllitidae is present with genera: Jura- phyllites Miiller, Meneghiniceras Hyatt, Harpophylloceras Spath e Galaticeras Spath. Only four genera of Pliensbachian age can be attributed to thè fam. Phylloceratidae; they are as follows: Phylloceras Suess, 1865 with thè two subgenera Phylloceras s.s. e Zetoceras Kovacs, 1939. Test with ornaments visible at low magnification; internai mould smooth, section elliptical, ovai or sublanceolate; E/L and L/U with or without phylloids (minor subdivisions of folioles). Partschiceras Fucini, 1923 ( = Procliviceras Fucini, 1923; Phyllopachyceras Spath, 1925). Test with well distinct riblets, sometimes with ribs and periumbilical ridges; inter nai mould with weak constrictions in thè inner whorls and with very weakly outlined ornaments on thè venter; E/L with phylloids; Hantkeniceras Kovacs, 1939 (= Calaiceras Kovacs, 1939). Test smooth; internai mould smooth with rare weak nearly straight constrictions; L/U with 2/3 folioles jointed at their base. Calliphylloceras Spath, 1927. Test with very well developed riblets along with strong rounded ribs; internai mould smooth with 4 to 8 deep arcuate constrictions; L/U with 2 folioles jointed at their base. -
First Record of Non-Mineralized Cephalopod Jaws and Arm Hooks
Klug et al. Swiss J Palaeontol (2020) 139:9 https://doi.org/10.1186/s13358-020-00210-y Swiss Journal of Palaeontology RESEARCH ARTICLE Open Access First record of non-mineralized cephalopod jaws and arm hooks from the latest Cretaceous of Eurytania, Greece Christian Klug1* , Donald Davesne2,3, Dirk Fuchs4 and Thodoris Argyriou5 Abstract Due to the lower fossilization potential of chitin, non-mineralized cephalopod jaws and arm hooks are much more rarely preserved as fossils than the calcitic lower jaws of ammonites or the calcitized jaw apparatuses of nautilids. Here, we report such non-mineralized fossil jaws and arm hooks from pelagic marly limestones of continental Greece. Two of the specimens lie on the same slab and are assigned to the Ammonitina; they represent upper jaws of the aptychus type, which is corroborated by fnds of aptychi. Additionally, one intermediate type and one anaptychus type are documented here. The morphology of all ammonite jaws suggest a desmoceratoid afnity. The other jaws are identifed as coleoid jaws. They share the overall U-shape and proportions of the outer and inner lamellae with Jurassic lower jaws of Trachyteuthis (Teudopseina). We also document the frst belemnoid arm hooks from the Tethyan Maastrichtian. The fossils described here document the presence of a typical Mesozoic cephalopod assemblage until the end of the Cretaceous in the eastern Tethys. Keywords: Cephalopoda, Ammonoidea, Desmoceratoidea, Coleoidea, Maastrichtian, Taphonomy Introduction as jaws, arm hooks, and radulae are occasionally found Fossil cephalopods are mainly known from preserved (Matern 1931; Mapes 1987; Fuchs 2006a; Landman et al. mineralized parts such as aragonitic phragmocones 2010; Kruta et al. -

The cephalopod fauna from the “coulées boueuses”, correlated with other macrofossil groups (belemnitoids, brachiopods, crinoids, echinoids etc.) and microfossil data (foraminifera) from the turbiditic unit, indicates Barremian age. The deposition of the allodapic limestones and marls in this interval occurred during depositionally unstable conditions which led to the forma- tion of turbiditic layers. The ammonoid fauna comprises 8 different genera, each apparently represented by a single spe- cies. The assemblage at the Serre de Bleyton section is dominated by ammonoids of the Melchior- ites-type. Ammonitina are the most frequent component (Melchiorites 52%; Holcodiscus 8%), followed by the Phylloceratina (Phyllopachyceras 3% and Hypophylloceras 2%), the Lytoceratina (Protetragonites 15%), and the Ancyloceratina (Anahamulina 10%, Karsteniceras 8% and Mac- roscaphites 2%). The ammonoid fauna consists solely of Mediterranean elements. Keywords: Cephalopoda, Ammonoidea, Barremian, Serre de Bleyton, SE France.

Pavia, Dipartimento di Scienze della Terra, via Valperga Caluso 35, I-10124 Torino (Italy); [email protected] KEY-WORDS - Systematics, Ammonitida, Lissoceras, Bathonian, Tethys. ABSTRACT - L. monachum has been frequently recorded in the Upper Bajocian and Lower Bathonian, but references in literature differ in morphological details as they are based on a juvenile and poorly-preserved holotype. In addition, the type of L. monachum comes from a bed affected by taphonomical condensation mixing fossils from Early and Middle Bathonian times, i.e. the biochronological meaning of Gemmellaro’s taxon cannot be specified with biostratigraphic criteria from the type-locality. These references are here revised and refused on the basis of two topotypes recently sampled at Monte Erice in western Sicily, which allow a precise morphological definition of L. monachum by means of architectural and sutural characteristics. The only acceptable biostratigraphic datum comes from a Lower Bathonian specimen from southern France. The differences from L. ferrifex, L. magnum, and L. ventriplanum are discussed. Finally, the suture-line of topotype PU111502 of L. monachum and those specimens from the Upper Bajocian of the Venetian Alps, here named L. aff. monachum, support the phyletic relationships between L. ferrifex and L. magnum through transitional forms of L. monachum aged for the Tethyan Early Bathonian.

Geologic Range: Early Cambrian to Holocene • Mode of Life: Marine and Freshwater
Class Bivalvia or Pelecypoda • Name: Bivalvia means " two" (bi) + " shells" (valvia). • Geologic range: Early Cambrian to Holocene • Mode of life: Marine and freshwater. Many species are infaunal burrowers or borers, and others are epifaunal. Class Gastropoda • Snails and slugs • Chief characteristics: – Asymmetrical, spiral- coiled calcareous shell. • Name: means "stomach" (gastro) + "foot" (pod). • Geologic range: Early Cambrian to Holocene. • Mode of life: Marine, freshwater or terrestrial. Class Cephalopoda • Squid, octopus, Nautilus, cuttlefish • Name: means " head" (kephale) + " foot" (pod). • Chief characteristics: – Symmetrical cone-shaped shell with internal partitions called septae – Shell may be straight or coiled in a spiral which lies in a plane. – Smooth or contorted sutures visible on the outside of some fossils mark the place where septae join the outer shell. Class Cephalopoda • Geologic range: Late Cambrian to Holocene • Mode of life: Marine only; carnivorous (meat- eating) swimmers. • Types of Paleozoic cephalopods: – Nautiloids – Ammonoids – Coleoids Nautiloid Cephalopods • The shells of nautiloid cephalopods have smoothly curved septa, which produce simple, straight or curved sutures. • Geologic range: Cambrian to Holocene Ammonoid Cephalopods • Ammonoid cephalopods have complex, wrinkled, crenulated septa, which produce angular or dendritic sutures. • Geologic range: Devonian to Cretaceous - all extinct. Ammonoid Cephalopods • There are three basic types of sutures in ammonoid shells: – Goniatite or goniatitic (septae
